Just went for a wee after running and there is blood in it.i have a kidney stone and also recently had vasectomy.any ideas as to what it could be?

Likely from stone: Should be discussed with urologist. Kidney stone may require treatment depending upon size & location of stone & any associated symptoms or signs of obstruction. Unlikely related to veasectomy. Good luck.

4 possibilities: 1. Stones. 2. Vasectomy, if recent blood can work it's way up. 3. Running - runners can get blood in their urine but usually only with extremes. 4. Other - i'd see a urologist to make sure there is no bladder tumor or infection. www.peedoc.com.
